The people of Brindavan used to conduct a special pooja every year and offer food to Lord Indra. Once, on Lord Krishna's advice, the people of Brindavan did pooja for Govardhana Giri (hill) instead. This irked Lord Indra, and the people had to face his wrath in the form of heavy rains. Finally, the people of Brindavan surrendered to Lord Krishna. Out of his benevolence, he gave shelter to the people of Brindavan by lifting Govardhana Giri and creating a roof above them.
